We divide 384757 by 21
Our goal is to divide 384757 by 21.

Let's proceed to step 1:
When dividing 3 by 21, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 21

Moving on to step 2:
The number 21 fits into 38 1 times, leaving a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 17 after subtracting 21 from 38.
Fetch the next digit (4) from the dividend, attach it to 17 and continue: 174 / 21

Advancing to step 3:
When dividing 174 by 21, we get 8 with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 18.0
Deduct 168 from 174 and we're left with 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 21

Let's proceed to step 4:
21 goes into 67 3 times with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 183.0
If we subtract 63 from 67, we get 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 21

On to step 5:
21 can be fit into 45 2 times, resulting in a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 1832.0
If we subtract 42 from 45, we get 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 21

Moving on to step 6:
21 can be fit into 37 1 times, resulting in a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 18321.0
If we take 21 away from 37, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 7:
160 divided by 21 is 7 with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 18321.7
The remainder is 13 after subtracting 147 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 8:
If we divide 130 by 21, we get 6 and a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 18321.76
Subtracting 126 from 130 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
The number 21 fits into 40 1 times, leaving a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 18321.761
Subtract 21 from 40 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 10:
When dividing 190 by 21, we get 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 18321.7619
If we take 189 away from 190, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 11:
21 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 18321.7619
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 12:
21 goes into 100 4 times with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 18321.761904
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 13:
The number 21 fits into 160 7 times, leaving a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 18321.7619047
If we subtract 147 from 160, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 14:
When dividing 130 by 21, we get 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 18321.76190476
If we subtract 126 from 130, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 18321.76190476, and the remainder is 4e-09.
